I am currently trying to apply the FindMinimum function to find the lowest energy of an expression. My current expression as of now is relatively complicated. It is the summation of 48 similar terms, ...

I'm running some analysis that requires the creation, row by row, of a large list of lists. The big list is called "Nodes" and it will ultimately contain hundreds of thousands of rows. The first few ...

This is probably a really simple fix, but I'm fairly new to Mathematica and am not sure how to do this properly. I know that trying to plot eigenvalues directly can be computationally expensive, so ...

I found a strange phenomenon that Mathematica is getting slow when I repeatedly called an external program by using ReadList. For example, the following code will display a significant increase of CPU ...

I have some computations that output a 300,000,000 element array of long unsigned ints, so about 2.4GB, in an h5 file. Mathematica handles files south of 2GB fine, albeit taking very long to import ...

This question (2 subquestions) is connected to How to speed up Select with MemberQ for large lists?
Q1: I would like to have an alternate version of the form below to do a multi-columns selection on ...
